Asap!! 85=2x(x^2+3)(2x+5) use quadratic equation

emmainna [20.7K]

Answer:

Step-by-step explanation:

85=2x(x^2+3)(2x+5)

85=2x(2x^3+5x^2+6x+15)

85=4x^4+10x^3+12x^2+30x

4x^4+10x^3+12x^2+30x-85=0

2x^2(2x^2+5x+6)+30x-85=0

shoot, this isn't possible with quadratic, maybe you can get somewhere from here

Can y’all please help if you know this I’m kinda lost !

Zepler [3.9K]

Answer:

Part A) x = 5

Part B) B = 113 degrees, C = 95 degrees. E = 95 degrees

Step-by-step explanation:

Part A:

We know that the sum of all angles in a pentagon are 540 degrees.

We already have two angles: 113 and 124 which add up to 237.

Make an equation out of all the information.

237 + 98 + 3x + 19x - x = 540

3x + 19x - x = 105

21x = 105

x = 5

Part B:

Substitute 5 for each x

measure B: 98 + 3x = 98 + 3*5 = 98 + 15 = 113

measure C: 100 - x = 100 - 5 = 95

measure E: 19x = 19* 5 = 95

Solve the following equations by using the Quadratic formula and answer the subsequent questions:

OleMash [197]

Answer:

Step-by-step explanation:

Note that x^2 - 6x + 9 = 0 can be rewritten as the square of a binomial:

(x - 3)^2

and the roots are found by setting this equal to zero and solving for x:

(x - 3)^2 = 0, or x - 3 = ±0, or x = 3 and x = 3

a) there are two equal roots: {3, 3}

b) the roots {3, 3} are rational

c) the roots {3, 3) are real

If you want to use the quadratic formula, proceed as follows:

1. Identify the coefficients of the quadratic: {1, -6, 9}

2. Find the discriminant b^2 - 4ac: It is (-6)^2 - 4(1)(9) = 36 = 36 = 0

As a general rule, if the discriminant is zero, the quadratic has two equal, real roots. These roots are rational: 3 can be rewritten as 3/1, which is a ratio.
